Consequently, we are able to ship our goods safely and reliably to almost anywhere in the world.

Neodymium Magnets (Neodymium Iron Boron Magnets), also known as NdFeB or Neo magnets, are the most widely-used type of rare earth magnet. It is the strongest type of permanent magnet made from an alloy of Neodymium, Iron, and Boron with the Nd2Fe14B tetragonal crystalline structure. It has replaced other types of magnets in many applications in modern products that require strong permanent magnets, such as motors in cordless tools, hard disk drives, and magnetic fasteners.

We can provide magnets of any size and almost any grade according to the specifications you provide. If you are in need of customized magnets, please mail to sales@zhijiangmagnets.com or fax your drawing to 0086 571 82871538 for more information. We'll get back to you within 1 to 2 businss days.
